Lightroom 5.0 - 5.3: noise reduction and sharpening upon export are still a problem!

Adobe, I hope you make sure this is fixed once and for all before releasing Lr5.4.

I still have way too many people downloading one of my plugins which I discourage (perhaps prematurely):

Lr50ExportAutoFix

Here is an excerpt from one user who provided feedback (in response to me saying he should no longer need it):

|> "Lr5.3 is still experiencing problems with images that are less than 1/3 of the original not being sharpened or having noise reduction applied fully. Your fix is still of value and works perfectly."

Maybe they're all crazy, or maybe there's still a problem. At first I thought the former, but now I'm leaning more toward the latter.

Cheers,
Rob

Is this problem 100% fixed in Lr5.4?

People are still downloading the Lr50ExportAutoFix plugin despite my claim that the problem should be 100% fixed in Lr5.4. Although none have swore (to me anyway) that there is still a problem, I can't help but wonder..

Anybody?

To all potential respondents:
* sharpening should *always* be evaluated at exactly 1:1 zoom ratio (no larger, no smaller).
* you need to choose desired level of output sharpening in order to maintain appropriate sharpness when exporting at reduced sizes.

If develop sharpening or noise reduction is not being applied at all, do tell. Likewise, if you have say standard output sharpening, and are viewing exports at 1:1 zoom ratio, but you believe exports are not "appropriately" sharpened - please speak up..

Adobe won't fix problems if they don't believe they exist ;-}.

Thanks,
Rob

I have Lightroom 4 and I have evaluated as you said "exactly 1:1 zoom ratio (no larger, no smaller)." And I have changed my Output sharpness to HIGH and there is NO difference in the exported picture and then the one exported with all of the changes made in output sharpness.

My Sharpening and Noise reduction are NOT being applied when viewed in the Library or when exported.

I seem to be late on the forums discussing this. Do you know of any updates regarding this problem? I noticed your comments on the LR 5 but figured your "plug in" was only for LR 5 and not LR4.

You might be sick of talking about this problem, but if you have any suggestions to add, I would be most grateful and glad to have something to try to fix this. This problem randomly started happening to me a month ago. I hadn't changed any settings or programs on my computer, which makes me think it's a bug. :(

Thanks for any help you might have!

Meredith - It sounds like this bug is not fixed in all cases, or there is another bug which is similar to it.

Is color noise reduction not being applied? (none at all?)
Is luminance noise reduction not being applied? (none at all?)

Is develop module sharpening not being applied? (none at all?)
Is output sharpening not being applied? (none at all?)

To be clear: it is not expected that develop module sharpening will have any affect whatsoever when exporting very large image areas at very small sizes - the output sharpening does it all in those cases, assuming it is enabled and working properly.

Adobe fixed the bug they knew of, in most cases, but if there is another, or other cases where it's not fixed, then you need to be very specific about what's going on, otherwise you may be ignored as yet another user sans clue ;-} - or just one of a few users with a very unusual problem.

Hopefully I'm wrong, and Adobe already knows there's a problem, and they're working on it, and all your and my efforts in this and other forums is being wasted at this point - dunno..

As you can see - Adobe has not commented here, and only 2 people have clicked the "+1 button". So, you're not alone, but also: not a lot of people are having the problem anymore (unlike the original problem, which had many "clicks" and comments..).

Color Noise Reduction is set at 25 and is being kept when moving from Develop to Library mode.

Luminance noise reduction is NOT being used.

develop module sharpening - Being set on 150 maximum.

Output sharpening is NOT being applied.

Honestly Meredith, trying to isolate bugs in Lr4 is not something I want to participate in. Adobe only cares about and will fix bugs in the latest version - it's what they use to test with, and is the code that gets fixed when there are problems. Step 1 for you therefore is to upgrade Lightroom - then let's talk.

Sorry if I seem like a hard-a, but that's kinda the reality of the situation..

If you "can't" upgrade, then you need to look at your system and critical data files etc., since Lr4 was behaving, then started misbehaving. Lr4 will *never* be "fixed".

This is the Develop mode view with the 150 sharpening applied.



This is Library view/Exported picture view that has lost the sharpening applied during the Develop mode.

What are "very small sizes?" I don't even know how decrease a picture to a certain size. All that I do or have ever done is export from a RAW file to a jpeg.

Hi Meredith - didn't see your last post until now.

if you export a 5000 x 3000 pixel picture at 500 x 300, then 100 pixels will be condensed into one. develop module sharpness settings will have very little if any impact on exported image (develop module sharpening is a relatively fine effect - does not span hundreds of pixels..).

if you export a 3000 x 2000 photo at 3000 x 2000, and view it at 1:1 (100%), then develop module sharpness settings will matter completely.

Those are two points - draw a line in between..

I honestly have no idea whether there is still a bug in Lightroom, which bites sometimes, albeit less than before, but clearly one of the reason's it's being reported more is due to higher rez images getting reduced on export.

Note: output sharpening is applied *after* resizing, and so has a very important effect on reduced size exports.

Hope that helps,
Rob
